Is dyspraxia genetic. I have dyspraxia my cousin has verbal dyspraxia my mum is certain her brother has it (undiagnosed) and a man who used to know my grandad told me he was a weirdo who never socialised and was always on his own so he might have it.

Is there any scientific evidence? or does it run in anybody else's family?

I think it has both genetic and environmental factors. I have dyspraxia and Aspergers Syndrome. My dad has dyslexic traits, my grandmother on my dad's side is classic textbook AS although undiagnosed due to age, her sister, who is now dead, was also classic textbook AS, their father was known for being dreadfully clumsy and was always covered in cuts and bruises from tripping and bumping into stuff so he could well have been dyspraxic, my 4 cousins from one family are all dyslexic, 2 of them also have ADHD and one of them is also somewhere on the autistic spectrum and my dad's cousin displays classic symptoms of AS so I think the genetic factor came from my dad's side but there are almost certainly environmental factors in my case too-my mum;s pregnancy with me was very traumatic, I nearly died from cot death at 5 months old and I sustained a head injury to the base of the head from my brother knocking me to the floor at 7 months old. I think, in most cases of dyspraxia, genetic and environmental factors come together to cause dyspraxia in a particular person.
